async api callback - there might be bugs

gistfile1.js

var asyncApi = asyncApi || (function(win) {

    var asyncApi = function(globalName, queueName, createGlobal) {

        var global = win[globalName];
        if(!global && createGlobal) {
            global = win[globalName] = {};
        }
        if(global) {
            var queue = global[queueName] || [];

            global[queueName] = {
                push: function(callback) {
                    // immediately invoke the callback
                    callback.call({});
                }
            };

            // execute any waiting callback
            for(var i = 0; i < queue.length; i++) {
                try {
                    queue[i].call({});
                } catch(err) { /* ignored */ }
            }
        }
    };

    return asyncApi;
})(window);

// Example:

asyncApi('monetajs', 'cmd', false);

// This code is running before API loads:
var theApi = theApi || {}; theApi.q = theApi.q || [];
theApi.q.push( function() { alert('the api is loaded - now i can use it'); });

// ... finally, the api is loaded, so it runs this code:
asyncApi('theApi', 'q'); // the alert will show now
